The invention provides an interactive game system and a control method, and relates to the field of game equipment designing. The interactive game system comprises wearable equipment and action capturing equipment, and mark patterns are arranged on the outer surface of the wearable equipment through circulation and comprise dark color parts and light color parts; the action capturing equipment isprovided with an infrared camera and a visible light camera which are controlled by a processor, and the infrared camera and the visible light camera have the same focal length and the same camera lens axis; the mark patterns are used for being collected by the infrared camera and the visible light camera at the same time and recognized by the processor. The game system and the control method cancapture game user actions with low costs and establish a role model which is synchronous with the game user actions in a virtual scene or a real scene.
